multiple classes in a single file : modifier private not allowed here

Question

I am not able to understand why this code doesn\'t compile:

class A {
    public static void main(String[] args) {
        System.out.println(\"hi\");
    }
}

p         


        

Answer 1

Make the B nested of A, like this:

class A {
    public static void main(String[] args) {
        System.out.println("hi");
    }

    private class B {
        int a;
    }
}

Or move B to a separate file. Also you can stick with default access level, this way the class can be accessed only from within the package:

class A {
    public static void main(String[] args) {
        System.out.println("hi");
    } 
}

class B {
    int a;
}
